Nimhans Neuropsychological Battery Ppt [better]

NIMHANS Neuropsychological Battery (NNB) is an indigenous assessment tool developed at the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore

. It was specifically designed to evaluate cognitive functioning in the Indian population, accounting for diverse cultural, linguistic, and educational backgrounds. Psychology Town Core Domains & Common Tests

The battery typically covers seven neuropsychological domains, frequently organized in presentations as follows: Key Functions Specific Tests Often Included Motor & Mental processing speed Finger Tapping Test, Digit Symbol Substitution Test Focused, Sustained, & Divided Color Trails Test, Digit Vigilance Test, Triads Test Executive Functions Planning, Flexibility, Inhibition

The NIMHANS Neuropsychological Battery (NNB) is a standardized set of clinical tests developed in India to evaluate various core neurobehavioral domains. Designed by Rao, Subbakrishna, and Gopakumar in 2004, it is widely used for the Indian population to assess brain-behavior relationships and identify cognitive, emotional, and volitional deficits. Core Cognitive Domains and Subtests

The battery typically takes 45 to 60 minutes to administer and covers lobe-specific and broad cognitive functions:

Motor and Mental Speed: Evaluated using the Finger Tapping Test for motor speed and the Digit Symbol Substitution Test for information processing speed. Attention: Focused Attention: Measured by the Color Trails Test. Time Required: The full battery can take 2

Sustained Attention: Assessed through the Digit Vigilance Test. Divided Attention: Evaluated using the Triads Test.

Executive Functions: Includes the Fluency Test, Working Memory (e.g., N-Back or Digit Span Backward), Planning, and Response Inhibition (e.g., Go/No-Go Test). Learning and Memory:

Verbal: Uses Ray’s Auditory Verbal Learning Test (AVLT) or story recall.

Visual: Assessed by Ray’s Complex Figure Test or stick construction. Fluency) Administration – Time

Visuo-Constructive Ability: Evaluated via design learning and stick construction tests.

Language and Focal Signs: Includes the Token Test for comprehension and specific checks for parietal focal signs like agnosia or apraxia. Versions and Demographic Norms

The NNB provides standardized normative data categorized by age, gender, and education level, which is critical as education significantly influences performance. NIMHANS Neuropsychological Battery for Children

4. Administration and Scoring

• Time Required: The full battery can take 2 to 3 hours depending on the patient's condition.
• Scoring: Raw scores are converted to Scaled Scores based on age and education. This is critical because education significantly influences cognitive test performance in India.
• Interpretation: Scores are plotted on a profile sheet. A "deficit" is typically noted if a score falls below the 5th or 10th percentile compared to the normative group.

3. Sensitive to "Subtle" Deficits

The battery is sensitive enough to detect "Soft Neurological Signs." These are minor abnormalities that might not show up on an MRI but affect daily life (e.g., slight clumsiness, minor memory lapses). This is crucial for early detection of dementia or degenerative diseases.
